" `"Beit" known that we, HAROLD WHTEMAN I'residing at Royston, W'imborne, and ARTHUR MCDOUGALL- DUoKnAM, resid- 'ing'fat Walden, "Alexandra ."Road, Upper i Parkstone in the county of Dorset, England, civil engineers, subjeotsof they King of--Great 'Britain, have invented lcertain new anduse- Improvements Relating to Vertical Retoy torts for the Destructive Distillationof Coal,

of which the following isa s ,eci'iicatiolri *,'Ininstallations' of vertica or substantially [vertical retorts for the destructive ,distillation` of coal,' suchas that described in British4 tent spec1ioation No. 16,497 of. 1903, the" 4bttorn of the retort 'is closed b va Water seal andthe coke lis lrem oved from t e retort bv a conveyor wlL'ch operates inthe water. he

rate 'atwhich the coal to be carbonized is fed into'the top of the 'retort is governed Aby the ratefat'w'hich 'the cokev is thus conveyed the coal in the retort. It thusv happens that the coke is necessarily submerged in the water .for a `comparativelylong time and absorbing more or less water comes deteriorated for some purposes. Thisdiihculty is obviously accentuated when a singlewater seal and a'single oonveyerserve several retorts.

Moreoveigit is difficult to work more than one retort properly "with a single convveyer, because the coke'ls notr'emoved to the 3 5.1.

same extent from each. l

The' present invention relates 'to improvements 1n installations of vertical retorts for.

'the earbonization of coal, whereby the conv veyer may be'operated at any desired speed,l so that the coke can'be Withdsawn from the Water seal before it has absorbed any appreciable quantity of water, and one conveyer may-be rnade'to serve fory the removal of .-'coke from several retorts.

the charge in the retort is supported by Va y y suitable support, such as a plate placed at a `Wh1ch dips beneath the surface of the ,waterv short distance below the open bottom of the vretort, preferably above the Water-line in the vWater seal. To facilitate this in thecase of a single retort, /the extension. of the retort is made of greater cross-sectional area than that of the retort. In the case of asettmg of vseveral retortsthere may be awater seal .Specification ofJiettersjPatent. i.

For thispurpose'v'l v `v common to all-and constituted by-an extenlsion'of the-setting and within this seal a sepa# rate plate to support the charge of each reis caused to move a rake or pusher at 'a' speed i proper to the rateat which the coke is yto* be removed fromvthe retort or retorts. f v l 'The invention is not limited"to' any-particular device for moving the rake or pusher; but itis obvious that the pusher maybe con- 4ven'iently mountedff' on a lrod Which-passes through the extension of the retort or rset-ting and receives a suitable, reciprocating move- `ment and that whe'nseveral retorts, in one setting are in line with each other, as is usually the case, one rod may carry the pusher for the plate kbelonging to each retort. The

Figurel is a` longitudinal vertical section ythe water seal therefor. 'Fig 2 is a crosssection on line 22 of Fig. 1. Fig. 3 is a lonvof' six vertical retorts'and the Water seal 44ofFig-3. l Referring to Figs. 1 and 2, ythe retorts aare set in `the settin b," the foundations b of into the water inthe sumpg. Beneath each retort there is' supported by the foundations b a late d, whose length preferably exceeds the diameter ofthe retort a. Through 'stuH- ing-'boxes f o n the end plates k of the/Water 'seal extends a hollow rod e, made up of three lengths joined together b'yhollow cylindrical pushers c." Water'is circulated through this rod and the pushers, and the rod -is given a reciprocating `movement b any suitable mechanism to cause the pusliiers to travel to and fro on the surface ofthe lates d, respectively, represented by the dlstance between c and c 1n Fig. 1 at a speed corresponding with the desired rate of c arbonization of the ycoal in the retort. The coke thus pushed from each plate falls into the conveyerv h, Whichopera'tes beneath the surface of the water in the sump g at any desired rate.

therefor, and Fig. 4 is a cross-sectiononline IiLt-QFWIMBDRNE;:ANDARTHUR? DUCKHA'MioF f UPPERprAsKSTQNE ENGLANDf i f "Patented oct. `23, `1996. Application filed 'November 15., 1905.

Across or along the plate or each plate coke thus pushed oil theplate falls onto the conveyer, which o erat'es in the Water below through a 'setting of'two vertical retorts and v8ol gitudinal' vertical section through ai setting which form the sldes of the water seal,.the ends ofthe latter being. formed of plates k, depending from 'the settingl and dipping 'at 'i A except where it dips lbeneath the plate 7c', soy

described.

In Figs. 3 and 4 letters ofreference which.

are the same as those used in Figs. l and 2 represent similary parts. The six retorts a are 1n two rows of threeyeach, and foreach row there is -a rod e, operated by aram o and` carrying three pushers c, one'or each plate 7d. These-plates are supported ,by girders m,

which also support Webs ln, of plates l, that form a hopper for directing the coke onto the 'conveyor In this casethe :upper stretch of the. conveyeris not immersedzin the lwater that the-coke is immersed in the Water only for. a very short stime. As the conveyer're.-

'moves the coke much .faster than it is ,dis-` lodged from the plates d by the pushers, the

liLo1 per made up of theplates Z never becomes therein` In Figs. 3 and 4 the pushers c are perforated to permit the water passed into the hollow rode to issue in sprays for cooling the plates d.
